Greetings - this is my take on the car antenna coop door. I used a NEMA rated electrical box from Amazon (<$20) along with some CN101 timers (~$10 each) and some cheap terminal strips from Amazon (~$12). Some wire, pulleys and a few other items and here we are! I added the light so I can get 14 hours of light on the hens during the winter and just in case I want to look in at night.
I created a schematic of the controls that shows how the wiring works.
Fun project - now to get the birds in there!
